' thereto.

The object of my invention is to provide an mexpensive,

efficient bond both electrically and mechanically and one which is well protected from derailed cars which are quite frequent in the case of mining operations.

My invention resides in the new and novel construction, combination and relation of the various parts hereinafter described and' shown in the drawings accompanying this specification.

In the drawings Fig. 1 is a side view of my invention and shows one terminal as applied to a rail base and its relation to the adjacent tie.

Fig. 2 is a top View of Fig. 1.

Fig. 3 is an end View of Fig. 2.

In the preferred embodiment of my invention I employ a body member 1 composed copper and which may be either preferably of stranded or solid. To each end of the body 1 is attached a tubular shaped sleeve 2 which may be of either ferrous or non-ferrous metal and may be formed from a seamless tubing or a sheet metal. I prefer to form the terminal of seamless drawn ferrous tubing. The terminal 2 may be applied to one end of the body 1 forming what is known as a stub end bond or it may be applied to each end of the body 1 forming across connecting bond or a bond spanning rail joints.

In forming the bond by cutting the body 1 in proper length and then placing in one or both ends a tube of proper length of material and then flatten a portion of the tubing with the body therein. The end of the tubing away from the body end is usually left with its original circular form. I may interpose between the end of the terminal 2 and the body 1 a separately formed sleeve 3 which I make preferably of considerably thinner material than that of the terminal tube and it p projects inwardly a distance suflicient to maintain it in position and it projects a distance outside of the terminal 2 to yieldingly support the body 1 adjacent the terminal 2 I and to protect the body 1 from the edge of j erably of copperor a copper alloy is brought the terminal 2.

of the part 9.

' of the body 1 that Having applied the terminal 2 to the end of the body 1 as described and having flattened the same, the end face 4 of the body 1 is left exposed and also the end face 5 of the terminal 2 such that welding or attaching I metal 6 may be fused to both the faces 4 and 5 in securing the bond end to the rail 7.

A portion of the terminal 2 with the body therein is now bent upon. itself forming the j parts 8 and 9 and the groove or slot 10 to receive the base of the rail 7 The other portion of the terminal with the body therein is then bent relative to the part 9 forming the part 11.

It is desirable to have the portion of the body between the terminals protected and reposed below the upper surface of the cross tie 12 and therefore I bend the part 11 downwardly and preferably backwardly relative to the part 9 such that the axis Y of the part 11 will be obliquely disposed to the plane X It is evident that the axis Y may remain at right angles to the plane X and stillthrow the body 1 below the surface of the tie 12, but by the particular arrange. ment shown I am able to shorten the length is required sufliciently to make a showing in both the cost of production and efficiency of the bond.

When the bond terminal is applied to a rail J base the end faces 4 and-5 form with the surface of the rail a receptacle to receive thev molten attaching metal 6 and to improve the efficiency of this receptacle, I bevel the end faces 4 and 5 and also curveothe same to form a concave surface. 1

If desired the part 11 may be bent directly back relative to the part 9 such that the axis TY will be parallel with the plane X, but

I prefer the construction shown although such modification will still give some protection to the bond body when installed and will further shorten the length of the body 1. In applying by bond I force the terminal uponthe base of the rail as shown in Fig. 1 and then the welding metal 6 in a fused condition is applied tothe faces 4iand' 5 of the bond and to the adjacent face of the rail 7. The application of the metal 6 which is prefabout by the use of the metallic are or the carbon arc process or by the use of the oxyacetylene flame by which the parts to which the fused metal 6 is to contact are likewise fused thus uniting the terminal, the body and the rail each to the other through the meoium'of the attaching metal 6. a Y

Having described my invention, I claim 1. A rail bond comprising a body and a terminal on each endand secured tothe body, the terminals consisting of a sleeve member extending back along the body for a predetermined distance, the body and terminal being flattened for a part of their length nearest the end and the other part changing to a circular section at the inner end of the terminal, a sleeve of less diameter than that of the inner end of the terminal projecting from the terminal along the body, the body and terminal each being bent upon itself for a part of its linear length and, forming a space between its adjacent bent portions to receive a rail base andthe balance of the, combined body and terminal being bent back relative to the other portion, each end face of the body being exposed at the outer end of the terminal and the end faces of the body and terminals being beveled and concaved to form a receptacle with the rail base to receive molten attaching metal in fused relation to the body, terminal and rail base.

2. A rail bond comprising a copper body and a ferrous tubular sleeve on each end and extending back along the body for a predetermined length, the body and its terminal each at each end being bent upon itself to form three portions resembling an S formation with two of the adjacent portions spaced to receive and grip a rail -base, the portions receiving the rail base being flattened and the extreme ends of thejbond each forming a receptacle with the rail base for the reception of molten attaching metal.

3. A rail bond comprising a copper bod and a ferrous ubular sleeve on each end and extending back along the body for a predetermined length, the body and its terminal each at each end being bent upon itself to form three ortions resembling S forma tion with two of the adjacent portions spaced to receive and grip a rail base, the ortions receiving the rail base being flattened and the extreme ends of the bond eac forming 'a receptacle with the rail base for the reception of molten attaching metal, the ends of the bond forming upstanding and curved walls of the receptacles.

4. A rail bond comprising a copper body and a tubular sleeve on an end thereof and extending back along the body, the body and its terminal each being bent back upon itself and flattened to form spaced portions to receive and grip the rail base, the end face of the body being exposed and the end of the bod; and terminal being eonc'aved and obliquely disposed to the flattened faces of the bond end to form with the rail surface a receptacle for molten attaching metal.

5. A rail bond comprising a body and a tubular shaped terminal member secured to an end thereof and extending back along the body, a partof the body and terminal each being flattened and bent back upon itself to form a flat sided slot to receive a rail base and the other part of the terminal and enclosed body being bent back relative to the adjacent part and having its longitudinal ax-is angularly disposed to the plane of the said adjacent part, the bond adapted to have its terminal and body welded to the rail.

;6. A rail bond comprisinga body and a tubular shaped terminal member secured to an end thereof and extending back along the body, a part of the body and terminal each being flattened and bent back upon itself to forma flat sided slot to receive a rail base and the other part of the terminal and enclosed body being bent relative tothe adjacent part, the bond adapted to have its terminal and body welded to the rail.

In testimony whereof I affix my signature.
